What is malware in computer – Alapan 1 Elementary School
Are you tired of popups, auto-open browser links, or auto-start programs on your computer or device? It might be infected with a computer virus or malware. For us to fully understand how we will deal with this attack or treat it with our devices. Let us first know the meaning of computer viruses or malware. What is malware in computer?
A malicious computer program (abbreviated as “malicious software”) is a file or code, usually delivered via a network, infecting, scanning, stealing, or running almost any attack that the attacker wants. And because computer malware comes in many forms, there are many ways to infect computer systems. This is software designed to disrupt normal computer performance. Malware is a common term for viruses, trojans, and other malicious computer programs that users use to infect systems and networks to gain access to sensitive information. This malicious program or software had the varied capability and focused on the following aims:
- Provide remote control for the attacker to use the infected machine.
- Send spam from an infected machine to unexpected locations.
- Investigate the infected user’s local network.
- Steal sensitive data.
- Your system crashes. This may come as a freeze or BSOD (Blue Screen of Death), the latter of which occurs in Windows systems after experiencing a fatal error.
- Your computer is slow. One of the side effects of malware is slowing down your operating system (OS), whether you are browsing the internet or using your local applications, the utility of your system resources appears to be unusually high. You may even see your computer monitor moving at full speed — which is a good indication that something is taking up system resources in the background.
- Your antivirus software stops working and you can not reopen it, leaving you vulnerable to malicious malware.
- You notice an unexplained loss of disk space. This may be due to a squatter of malicious malware, hidden in your hard drive aka bundleware.
- You lose access to your files or your entire computer. This is a sign of infection with ransomware.
The most simple way to remove malicious computer programs is to use the default malware remover of Microsoft Windows OS.
